IMPROVEMENT IN cARmAGE-JACKS.

Specification forming part of Letters Patent N'o. 47,628, dated May 9, 1865.`

To aZZ whom it may concern:

Be it known that I, R. FINK, of Batavia, in the county of Kane and State of Illinois, have invented a new and Improved Carriage'Jack; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawing, forming part of this specification.

The drawin g represents a side sectional view of my invention.

The object of this invention is to obtain a simple and efficient jack which may be applied to the a-Xles of either light or heavy wheel vehicles, and both to the front and back axles of the same vehicle, for the purpose of raising the axles to admit of the ready removal of the Wheels and replacing the same for lubricating purposes.

A represents a base-plate, having one or more uprights, B, secured to it to support a lever, O, the fulcrum-pin a of which passes through the former.

The base-plate A has a series of notches, b,

made in its upper surface, said notches ex-` `tending from the center of one end toward the uprights B and D is a bar, one end of which is connected by a joint, c, to the short arm of lever O near its end, the barD engaging with the notches b and having a greater or less inclination at all times when supporting the lever U. The lower end of barD is connected by a chain or cord, E, with lever O, as shown in the drawing.

On the lever C there is placed a slide, F, having a notch or recess, d, in its upper surface to form two different bearings, e e', for

axles. This slide F is provided with a plate,

f, at each side, and these plates extend down by the sides of the lever O and have their lower parts bent inward or toward each other to fitin an oblong slot, g, in the lever, the len th of said slot determining the length of the movement of slide F.`

By this means the slide F may be adjusted on the lever to su1t axles of different heights. The bearing e is designed for the axles of heavy Vehicles and the bearings e' for those of light vehicles. instead of a sliding one, F, but the latter is far preferable.

When the slide is adjusted under the axle, the longer arm of lever Cis pressed down, and the bar D, in consequence of itslower end engaging with the notches b, sustains the lever and the weight upon slide F. y

The jack is disengaged from the axle by pullin g the cord or chain E, and thereby freeing the lower end of bar D from the notches bl By this arrangement a very simple, economical, and durable lifting or carriage jack is obtained, and one which may'bevery readily``` I applied to and detached from the axles of all ordinary vehicles.

I claim as new and desire to secure by Letters Patentl1. The lever O, in connection with a fixed bearing or a sliding one, F, bar D, and notches b in the base A, and for the purpose specified.`

2. The cord or chain E, connected tothe bar D and lever G, substantially as and for the purpose set forth.
